Pam showed me Tom's selfie, "Tom's a good-looking young man. I knew the picture would excite him; my cock stiffened when I took the pictures. Do you quietly want to let him know you could be available?"
"Darling, let's go home. Mummy will make you stiff again and we can talk about it in bed. The thought of it excites me, but I'm so happy and satisfied with you. There's no way I want to give you up. I'm still tingling from this morning and I want the same again. After that we can think how we reply."
As I paid the bill, I felt sure Pam was interested in her son, Tom. Maybe she'd be interested in a double penetration from both of us? Pam was the only woman I've ever had who could satisfy me completely. There was something so special about her I didn't want to lose her.
We walked home. Barry, you're making me so horny now all I want is the king, I had my arm around Pam fondling her massive right tit. I've decided to reach out to Tom and show my appreciation for the compliment. I'd love for him to visit, but he must assure me he'll keep any contact with me a secret from his father. I'll also tell him you're my lover. Are you ok with that? I'll let you read it before I send it."
In the apartment Pam stripped naked and so did I, she lay on her bed with her legs spread as she typed her reply to Tom. I went down on her. I was sucking her huge clit as she wrote. She was now pushing her pussy hard against my mouth.
Pam let me read what she'd written, "Dear Tom, thank you so much for your lovely birthday message. I was so happy when I read it. I'm also happy you liked the picture. You're more than welcome to come and visit me, but you must promise me you never tell your father that you have any contact with me at all. Barry and I are now in a relationship. He spends a lot of nights in my apartment. Please never tell your father about him. We are going to France on Friday for nine days. I'm looking forward to our trip as I love being with a younger man. If you promise me, you'll never tell your father anything about me that would make me so happy. If I can trust you, we can be more open in our messages. Another condition, any pictures I send you are for your eyes only. Looking forward to hearing from you. All my love, mum xx."
I smiled when I read it, "Mummy's naughty. When he replies, you could tease him a bit more by sending the kimono picture. You should also ask him about any relationships he's had. I'm sure he'll reply soon."
"I have the feeling he will, too. The kimono picture is a good idea. I also bought a very skimpy bikini, my big melons spill out of the top. There's not much to the bottom. It's tight fitting and shows my Camel's Toe to perfection. Let me give you a nice gobble, then I want a hard birthday fuck. I want you to know that mummy's enjoyed her birthday with you."
Pam gave me a great gobble. My cock was dripping with her saliva. She could do some wonderful things with her lips and tongue. When she gobbled, she would always cum at least once. The other thing I'd noticed was when she sucked cock, it aroused her a lot. She told me she wanted a hard and deep doggy style ride. That's what she got. She had three massive orgasms; I had only one, but it was a good one. I spurted powerfully six times against her cervix. We fell asleep in each other's arms.
The next morning, we made love again, showered, and had breakfast. Pam said, "I should check my mobile, I wonder if he's replied?"
She went to the bedroom and came back with a smile on her face, "I think he's interested. Let me read it again, so I'll know the best way to reply."
Pam read it again and handed me her smartphone, "Have a read and tell me what you think?"
"Dear Mum, thank you so much for the invitation. Your tempting offer is too good to resist, I would love to take you up on it. I would love to spend time with you and get to know you better. I hardly speak to dad. He spends no time with me. He wanted me to come into his business. As I wanted to be independent. I told him I wanted to study dentistry. I know I'll get good grades in my exams."
"My word is my bond. I promise you that anything we do together, dad will know nothing about it. There's a small group from the school that is having a European tour during the holidays. They'll be away for ten weeks. I'll tell you a little secret which has conditions. You never tell dad. As you know, dad has an apartment in Chelsea. It's twenty minutes from my school. I occasionally go there on weekends. One of dad's girlfriends is usually there. He's got a lot of girlfriends. In the last six months, I've had several of dad's girlfriends. If I ask one of them to suggest that I want to go on a school European trip. I'm sure he'll finance it. I could be with you for ten weeks during the summer. If you like this idea, please let me know as soon as possible, as I need to get one girl to do special treats for him, so he'll agree."
"If this works out, I'm sure it will, as the only thing that dad and I have in common is we both like big tits. If things work out between us during the summer, I could apply to a Dental College in your city? Let me know if you'd like me to go on the European trip to your apartment? Looking forward to your reply. All my love, Tom xx."
I smiled at Pam, "I think he's more than interested. He's opening up, I like his style. He's resourceful, like his mum. We could give him a summer job in the centre. You'll have to flirt with him and also tell him how good you feel when you're around me. Let him know he can't have exclusive rights with you."
Pam asked me to make her a coffee, then she started typing. Ten minutes later, she let me read her reply.
"My darling Tom, ten weeks would be wonderful. Get your dad's girlfriend to say that the European trip would be an exciting experience for you. Can I ask how old are his girlfriends and does he have many? I haven't told Barry that I've invited you. Don't worry, I will do some special things for him. I'll tell him I haven't seen you for over six years and it would be wonderful if you would come and spend some time with me. I need to go to work. Write soon. All my love, Mum xxx."
